UNITED STATES RICHARD MAX EATON. OF NIAGARA FALLS, NEW YORK.

FLASH LIGHT.

Application filed March 18J 1920. Serial No. 366,892.

To all whom t may conce/fn Be it known that I, RICHARD MAX Error, acitizen o'r the United States, residing at Niagara Falls, in the countyof Niagara and State `ot New York, have invented certain new and usefulImprovements in Flash Lights, oit which the `following is a full, clear,and exact description.

The principal object of this invention is to provide a switch, speciallyadapted for use in connection with portable electric search lights` bythe operation of which the lamp may be caused to glow temporarilyproducing a single flash, extended in duration by holding thebuttondepressed, or by shifting the position of the button, to cause acontinuous emission of light.

A further object is to provide an effective guard for the single buttonused. protecting it against inadvertent displaceu'ient, means also beingprovided for maintaining the button in either of its adjusted positions.

These and other objects, such as simplicity ot structure, assemblage andoperation are attained by the novel construction, combination andarrangement of parts hereinafter described and shown in theaccompanying` drawings, forming a material part of this specification,and in which:-

Figure 1, is a top side elevational view of a search light made inaccordance with the invention.

Figure 2 is a longitudinal sectional view taken on line 2 2 of Fig. 1.

Figure 3, is an enlarged fragmentary sectional view taken through theswitch, con-- tact and support.

Referring to the drawings in detail, the

ynumeral. 10 designates the cylindrical hollow body of a conventionaltype `of search light or electric torch, the Same being made otnonconducting material and adapted to be grasped by the hand.

Engaged by the rivet 13 is a metallic strip conductor 30 secured at itsinner end by a similar rivet 31.

Another strip conductor 35 is arranged in register with the strip 30.its free front end 35 extending into the head 11 so as to make contactwith the exterior of the retlectorlS.

The strip 35 is firmly held in engagement to the interior of the body 10by another tubular rivet 36, immediately rearward of which the strip issheared to produce a tongue 38 bent to extend outward and upward throughan opening 39 formed in the wall oitl the body 10, the extreme end ofthe tongue resting on the outer head of the rivet 36. y

The end 40 of the strip 35 is also turned outwardly and upwardly,extending through another opening 41 in the wall of the body, as canbest be seen in Fig. 3.

A thin metallic casing or housing 44 is provided with Hanged feetextensions 45 and 45', held securely to the exterior ofthe body bv therivets 31 and 31', and formed longitudinallyl in the casing 44 is a slot46, adjacent to the rear end of which is a raised abutment or guard 47.

Elidably engaged in the slot 46 is a stem 48 having an extendingoperative but-ton or head 50, the inner end of the stem 48 being rivetedor otherwise tirmly secured in a plate 51 having an upturned angular end52 engageable within the recess formed in its abutment 47, as shown inFig. 2, thereby locking the stem, button and plate.

The outer end of the plate 51, which is made of spring material ofconducting nature. is turned reentrantly, forming a bend 53, from whichextends a spring contact 54, disposed below the plate 51 and terminatingin a curved strip 55, slidable on the exterior of the non-conductingbody 10 and adapted to act as a detent when over the opening 39, holdingthe parts in a forward position.

In operation, when no light is required, the button 50 is moved to therear until the end or detent 52 engages in the recess of the abutment 47at which time the abutment, ex-

tending as it does flush or level with the top of the but-ton, acts asaprotecting guard against inadvertent contact or pressure on the button.

If a lash or temporary light is desired, the button 50 is manuallydepressed, causing vthe outer end of the plate 51 to make contact withthe element 40 of the conductor strip 35, thus conveying current fromthe battery through the ferrule, cap and strip 3() to the end 40 andthence through strip 35 reflector 18, socket and stem to the bulb 20,the inner contact of the stem being in electrical contact with the otherpole o'lf the battery.

Thus during the depression of the button a light 'is obtained of atemporary nature; if however, a continuous light is required the button50 is depressed and moved towards the head, causing the spring contact54 to engage the tongue 38 and form a circuit in the manner beforedescribed, the device mak ingdirect and positive metallic eirouit ourtacts throughout.

laving thus desoribed my invention and .set `forth its purpose7 mannerot construction and application, what l claim as new and desire tosecure by Letters Patent,
